Abstract (en)
[origin: EP3308855A1] The present invention relates to a method of preparing a catalyst for oxidative dehydrogenation. More particularly, the present invention provides a method of preparing a catalyst for oxidative dehydrogenation providing superior selectivity and yield for a conjugated diene according to oxidative dehydrogenation by constantly maintaining pH of a coprecipitation solution using a drip-type double precipitation method to adjust an ±-iron oxide content in a catalyst in a predetermined range.
